Upload Function - A server error occurred while uploading the file

akp982

While trying to use the upload function for images with DataTables 1.8 I'm getting the below PHP error which I can't seem to work out the cause off.

Has anyone seen this before / got any thoughts on how to fix?

[13-Feb-2019 05:01:56 Europe/Dublin] PHP Fatal error: Uncaught Error: Function name must be a string in C:\inetpub\CommsScreens\Admin\php\lib\Editor\Upload.php:382

It's to do with my validator statements. I've managed to turn them comment them out and move onto the next issue for now

Hi @akp982 ,

That looks OK with the validator statements. The only thing I can think of is whether you didn't include the full list of use so Validate is unknown. Take a look at the "Server Script" tab on this page here - it would be worth comparing to your script.

Hope that does the trick,

Cheers,

Colin
